Foreign Office Architects was founded by Farshid Moussavi and Alejandro Zaera Polo in 1992. Until 2000 they were Diploma Unit Masters at the AA, combining teaching with several other projects, most prominently the large-scale development of Yokohama International Port Terminal. FOA have been engaged in many different projects since completing the YIPT, including the publication of a monograph, an exhibition at the ICA, and winning the commission to design the new BBC Music Centre in London. In this lecture Alejandro Zaera Polo and Farshid Moussavi focus on the connections between the way buildings are understood publicly and how they are built.
